Traffic Report  on 30 November '12

Two objects reported inside ten LD

There are two objects reported moving within ten lunar distances (LD) of Earth today. 2012 WH1 is outbound from 7.70 to 8.16 LD, and risk-listed 2012 WR10 from 9.25 to 9.93 LD. Approaching next, 2009 BS5 arrives inside ten LD on December 7th.

This report was generated at 1728 UTC with follow-up in today's DOU MPEC for 2012 WH1.


Notes: Ten times the distance to the Moon (ten LD) has no astronomical significance but is a useful reporting boundary. Object distances are interpreted by A/CC from JPL Horizons data. See also current sky chart and object details (alt-details), ephemerides, and today's timeline.
